U need to find the equation of the line....and once u do that, sub in 0 for x and solve for y
Answer:
x = 8
Step-by-step explanation:
→ Add 16 to both sides
x = 8
We know that
if ∠WCR=49°
then
measure arc WR=49°-------> by central angle
circumference C=2*pi*r
for r=7 in
C=2*pi*7-----> 43.96 in
if 360°(full circle) has a length of----------> 43.96 in
49°---------------> x
x=49*43.96/360-----> x=5.98 in
alternative method
applying the formula
L=(∅/360°)*2*pi*r
where
∅ is the angle in degrees
r is the radius
L=(49°/360°)*2*pi*7------> L=5.98 in
the answer is
5.98 in
280 divided by 7 = 40 pages every night
(28/7=4, add a zero)
B should be the answer Hope this helps.
